Bragging?

I heard something very interesting recently: When men get together, they tend to brag. When women get together, they tend to discuss problems. Doesn't that mean that maybe men are focusing on the positive while women are focusing on the negative? Of course it is almost always an uplifting experience to get together in a gender group this way and just "be". But I do see that women tend to discuss "issues" and men tend to want to forget them and try to just have a good time. I realize these are sterotypes, but I thought this was a very interesting concept.
